I’m wondering if I’m making the right approach when I’m trying to calculate the power consumed by the diode in the circuit.
Here is the problem:
So my approach is:
Power loss by diode $$V_f \times I_f$$ where
\$V_f\$ = Diode forward voltage drop.
\$I_f\$ = The current flowing through the diode.
So the first thing I did was to calculate the current
$$I = V/R = 5/1000 = 5 mA$$
And then I use $$ V_f \times I_f= 2 \times 0.005 = 10 mW $$
Is this correct? I feel like there is more to the problem with the fact that it states ”red color light”. Should I check on a sheet or similar?
